化学改性生物柴油制备润滑油基础油

用生物柴油来制备环氧生物柴油,然后在D001树脂的催化作用下,环氧生物柴油和异辛醇进行异构醚化开环反应,合成的改性生物柴油即为润滑油基础油.通过红外光谱对原料和产物的结构进行表征,并对合成的润滑油基础油的性能与环氧生物柴油和150SN矿物润滑油进行了比较.结果表明,所合成的润滑油基础油热稳定性好、黏温性能好、黏度指数大、氧化稳定性良好、承载能力和抗磨性能较好.同时考察了D001树脂重复使用性,发现重复使用5次后仍具有较高催化活性.

Preparation of lubricant base stock through chemical modification of biodiesel

The epoxidized biodiesel (EBD) was prepared with biodiesel (BD) as raw material, which was then subjected an etherification ring opening reaction with 2-ethyl hexanol over the D001 resin catalyst; the resultant product can be used as the lubricant base stock. The products and material used were characterized by FT-IR and TG; the properties of as synthesized lubricant base stock were compared with those of EBD and the lubricant from 150SN mineral oil. The results showed that the as-synthesized lubricant base stock is excellent in terms of thermal stability, viscosity-temperature behavior, viscosity index, oxidation stability, and wear resistance and loading capacity. Moreover, D001 resin as a catalyst exhibits good reusability; it remains high active after being used for five times.
